何らかの事故により或いは呼吸装置使用者の過失で、雄部が押し込まれ且つ戻り方向へ捩じられて、雄部と雌部の接続が解除され、フィルターが面体から離脱する事態は発生し得る。
従って本発明は、呼吸装置の面体とフィルターとの間の脱着コネクターであって、押して捩じるバヨネット式接続機構を備える脱着コネクターにおいて、事故や過失によるフィルターの面体からの離脱を効果的に阻止できる脱着コネクターを提供することを目的とする。 Due to some accident or by the negligence of the breathing apparatus user, the male part can be pushed in and twisted in the return direction, the male part and the female part can be disconnected, and the filter can be detached from the facepiece.
Therefore, the present invention is a detachable connector between the facepiece of the breathing apparatus and the filter, and is a detachable connector having a bayonet type connection mechanism that pushes and twists, and effectively prevents the filter from detaching from the facepiece due to accident or negligence. An object of the present invention is to provide a removable connector.
上記課題を解決するために、本発明においては、呼吸装置の面体とフィルターとの間の脱着コネクターであって、押して捩じるバヨネット式接続機構と、弾性体の穴にピンが嵌合するロック機構とを備え、フィルターの接続時には、バヨネット式接続機構の接続動作とロック機構のロック動作とが同期し、フィルターは接続と同時にロックされ、フィルターの取り外し時には、ロック機構のロック解除動作がバヨネット式接続機構の接続解除動作に先行し、フィルターのロックが解除された後に、フィルターの接続が解除されることを特徴とする脱着コネクターを提供する。
本発明に係る脱着コネクターにおいては、フィルターの取り外し時には、ロック機構のロック解除動作がバヨネット式接続機構の接続解除動作に先行するので、すなわちフィルターの取り外しが独立した二つの解除動作を必要とするので、事故や過失によるフィルターの面体からの離脱を効果的に阻止できる。
本発明の好ましい態様においては、ロック機構の弾性体は、両端が固定され両端近傍に径方向外方への突出部を有する湾曲した帯状体であり、穴は帯状体の長手方向中央部に形成されており、ピンはバヨネット式接続機構の接続動作の初期には帯状体の突出部の一方に径方向内方から対峙しており、バヨネット式接続機構の接続動作の進行に連動して帯状体の中央部へ相対移動して、バヨネット式接続機構の接続動作完了時に帯状体の穴に嵌合し、帯状体の両端近傍の突出部が径方向内方へ押し込まれることにより長手方向中央部が径方向外方へ突出して穴とピンとの嵌合が解除される。
帯状体の両端近傍の突出部を押し込み、帯状体の長手方向中央部を突出させて、穴とピンとの嵌合を解除するロック解除動作は複雑な動作であり、事故や過失で当該動作がなされる可能性は低い。この結果、事故や過失によるフィルターの面体からの離脱が効果的に阻止される。
　本発明の好ましい態様においては、ロック機構の弾性体はフィルターに取り付けられており、ロック機構のピンは面体に取り付けられている。
　本発明の好ましい態様においては、ロック機構の弾性体は面体に取り付けられており、ロック機構のピンはフィルターに取り付けられている。
ロック機構の弾性体とピンとの相対位置関係は、上記何れでも良い。
　本発明においては、上記何れかの脱着コネクターを備えることを特徴とする呼吸装置の面体を提供する。
